SPECIFICATION forming part of Letters Patent No. 764,224, dated July 5,1904.

Application filed April l2, 1904. `Serial No. 202,800, (No model.)

`overhead current-collecting devices for trolley-ears, and particularlyfor higlrspeed heavy multiple-unit electric trains for interurbanservice. Atrolley suitable for such use must be capable of taking aheavy current and of operating at high speeds on curves as well as.

on a straight track and be strong enough to withstand the tremendouslateral strain under such circumstances, and where the trains run insubways it must accommodate itself to the often low head-room and mustbe capable of passing under crossings with regular trolley wires whilethe train is at full speed. Besides satisfying these conditions myinvention has for its object the construction of a trolley that will notleave the overhead conductor in any direction nor while the train isrunning at any speed; that will permitthe train to be run in eitherdirection without reversal ofthe trolley; that will be durable and willreduce the wear on the trolley-line and simplify and cheapen overheadconstruction, present trolley wheel methods requiring' an expensivearrangement of overhead frogs, Sac.; that will permitrapid switching,and which will be practically noiseless in operation.

The invention consists of the parts and the construction and combinationof parts, as hereinafter more fully described and claimed, in which-Figure l is a side elevation of my device. Fig. 2 is an ond view ofsame. Fig. 3 is one end of the trolley-roller, shown in section withguard-support. Fig. l is an end view of Fig. 3. Fig. 5 is a front viewshowing clamping Figs. 6 and 7 show upper and lower frame-bearings aswould appear with frame in alinement. i

Where cars are to be operated in multipleunit trains, it isimpracticable to employ the ordinary trolley pole and wheel by reason ofthe liability of the wheel leaving the wire and damaging both theoverhead gear and the trol-` ley-pole.

My trolley comprises a jointed double diamond-frame lazy-tongs structure'composed of Efour rectangular frames A A B B', preferably of angle-ironand suitably b'aced and `hinged together and operating so that thecontact member or trolley-roller 2, which is i supported between theupper edges ofthe two g teprnost frames B B, may rise and lower toaccommodate itself to the varying heights of the trolley-wire. The twolower frames A A are separately pivoted at their lower ends onindividual shafts 3, mounted in a fixed sup,- ,port, and these frameshave interengaging segmental gears ll, whereby each will partake ofprecisely the same pivotal movement.

Where the respective pairs of frames A B and ends of the upper framesB Bas carrying rela-` i tively long aXially-alined sleeves 5 andthe up-,per ends of the lower frames A A as carrying lthe perforatedoil'setjournal parts 6, which are adapted to iit over the outer ends ofthe sleeves 5. A pivot-rod 7 is adapted to be slipped through each setof sleeves and journal parts 6 and to be held in place by suitablemeans, as the nuts 8. The upper and lower frames are thus free to pivoton the rods 7,- the sleeve 5 affording' a sufiiciently long bearing togive rigidity to the structure and enable it to with stand the severestrains it is subjected to,par- `ticularly when the train is roundingcurves at high speed. A single-framestructure of this character isabsolutely impracticable, as it would lack necessary strength. Thisentire device is designed toward overcoming the inherent structuraldefects of other trolleys of this class.

The upper ends of the topinost frames B B terminate in interengagingsegmental gears 9, which turn on individual pivots l0. 'lhc inner endsof the latter arefastened in the castings 11, which support the ends ofthe non-rotatable axle 12 of the trolley-roller 2. The outer ends of thepivots l() are secured in castings 13. The upper portions of thecastings ll and 13 have downwardly and out IOO wardly inclinedprojections 14, disposed each in the same plane,te which the lateralinclined curved guards or pick-ups 15 are made fast. When the guardshave been bolted to the inclined projections 14, the castings are unitedinto a rigid structure and give proper support and bearing f or thegears 9. These gears are essential for the maintenance always of thevertical position of the guards. The rolleraxle 12 is clamped in thecastings 11 by means of the blocks 16 and nuts 17, screwing onto studsin the castings.

The trolley-roller is especially designed to withstand excessive weareither of itself or the trolley-wire, to avoid heating at the bearings,and to be as noiselessas possible. It consists of an outer tubing ofbrass or other suitable conducting material secured at each end to aninterior hub' portion 18, provided with suitable graphite bushings 19,which run on the stationary axle 12. The hubs are pro'vided with annularoil channels or pockets 20, which may be filled from time to timethrough an opening 21 at each end of the roller and normally closed bymeans of a macliine-screw set into the periphery of the roller. 22 is acylindrical partition or rollv of fiber or like nonresonant matterextending between the hub `I claim, and desire to secure by LettersPatportions 18 and out of contact with the axle.

23 represents fiber disks, and the space between the roll and disks andouter brass tubing is packed with waste, as shown at 23". rlhisconstruction very ef'fectually deadens all noise, while the wear on thebearing parts is reduced to a minimum.

, In case a roller or roller-axle is toy be taken out and replaced itcan be quickly done by loosening and removing the clamps 16.

To hold the contact-roller to the trolleywire, a seriesof strongtension-springs 24 are arranged with one end secured near the bottom ofone of the lowei` frames, as A', and the other secured to brackets 25near the top of the other lower frame, so that the springs will alwayslie in ay plane approximately or nearly parallel with' the latter frame.This way of attaching' the springs has been found' quite important',- asit gives practically an even tension on the trolley-wire at all'ordinary working heights, since by attaching the lower ends of thesprings close to the pivot of the two lower frames the arcv describedYby those lower spring ends is subjectv to very little variation, whereasto run the springs horizontally would cause them tov be continuallyopening and closing through quite a wide range, while the up-and-downmovement of the rol-ler might be comparatively slight. The tension ofthe springs may be adjusted by an eyebolt 26.

The contact between the roller and thel metal conducting trolley-framevis effected by the usual frictional contacts 27.

28 is a block for the purpose of causing the springs 24 to exert atension in a direction tearing things to pieces.

such as to straighten the trolley-frame after it has been abnormallydepressed.

The lateral guides or guards 15 are inclined outwardly and downwardly,and their upper surfaces are substantially continuous with the top edgeof the trolley-roller, so that the trolley-wire may easily pass off overthe ends of the roller or run up the guards onto the rollers, as wherethe train passes from a single track to double track, or vice versa.

' Without these guides or guards it would be impossible for the rollerto pass, for instance, from a branch to a main-line trolley-wire,without jamming in the fork of the wire and The guards act as pick-upsfor the lower wire and lead it gradually and automatically onto theroller. The guards are essential to the operativeness of the rest of thedevice.

Among the points to be particularly noted in the present structure arethe double frame, its means for bracing against lateral strain, themeans for supporting the trolley-roller and for supporting thetrolley-guards, the

lspecific roller construction, the particular form of guards, and thespring-tension devices for the frame.
